Jack Leiter is a starting pitcher for the Texas Rangers. In 2026 he struck out 83 batters over 80.0 innings across 15 appearances, 15 of them starts, going 3-7. His ERA of 5.29 was 26.5% higher than the league average of 4.18 — 13th of 16 on his team, and 428th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 4.77 FIP suggests he pitched better than his ERA shows. He missed bats on 25.4% of swings (12.2% of every pitch he threw), walked 9.9% of the batters he faced and struck out 23.4%. His 0.4 dbWAR is built from that FIP rather than runs allowed, so it credits him for what he controls and not for the defence behind him.
